Question

Darnell and Hector ride their bikes at constant speeds. Darnell leaves Hector’s house to bike home. He can bike the 8 miles in 32 minutes. Five minutes after Darnell leaves, Hector realizes that Darnell left his phone. Hector rides to catch up. He can ride to Darnell’s house in 24 minutes. Assuming they bike the same path, write the liner equation that represents darnells constant speed

Answer 1

Answer:

  s = (8 mi)/(24 min/(60 min/h))

Step-by-step explanation:

Let s represent Darnell's constant speed. We know that speed, distance, and time have the relationship ...

  speed = distance/time

Darnell's speed in miles per hour is ...

  s = (8 mi)/(24 min/(60 min/h)) . . . . equation representing Darnell's speed

_____

This simplifies to ...

  s = 20 mi/h
